Built on a high-precision 4-in-1 antenna architecture, the T81 combines a multi-band GNSS antenna, 4G antenna, Bluetooth antenna, and Wi-Fi antenna within a single rugged housing. It integrates an advanced GNSS module and high-performance multi-frequency receiver, ensuring fast convergence times, stable signal tracking, and reliable positioning performance even in complex field environments.
Comprehensive positioning solutions for any environment
Navynav smart antenna T81 provides flexible positioning solutions to ensure stable, high-accuracy results under all operational conditions, with or without network access. No matter the connectivity scenario, T81 ensures stable and accurate positioning anywhere, anytime, bringing flexibility and confidence to every operation.
- Network available – RTK solution with Ntrip
For connected environments, T81 delivers centimetre-level RTK positioning (2 cm + 1 ppm) using network-based corrections via Ntrip. This solution ensures rapid initialisation and robust accuracy across wide agricultural or construction sites.
AI is not just a technology — it has dramatic societal implications
- No network – RTK solution with base station
When operating in remote areas without network coverage, T81 still achieves centimetre-level RTK precision (2 cm + 1 ppm) by connecting directly to a local or self-built base station, ensuring reliable guidance and control.
- No network and no base station – PPP solution
T81 also supports precise point positioning (PPP), including E6-HAS services, offering 20 cm accuracy without the need for an internet connection or base station. This enables uninterrupted operation in isolated or network-limited environments – truly connectivity-independent precision.
- L-Band supported
In addition, the new smart antenna now supports L-Band correction services, with the accuracy up to 1.5 cm. Both L-Band and RTK share the goal of eliminating common positioning errors such as signal delays, satellite clock drift, and orbit deviations. The difference lies in data delivery: RTK relies on ground-based networks to transmit correction data, while L-Band uses satellites to broadcast corrections globally. This satellite-based approach ensures high-precision performance even in rural, mining, or agricultural regions where 4G/5G coverage is weak or unavailable – offering connectivity-independent accuracy.
Expanded connectivity and interface options
T81 maintains compatibility with a wide range of agricultural and industrial control systems through its standard interfaces – RS-232 Ports, CAN Bus, Bluetooth, 4G, and radio. In this new generation, Navynav further enhances system integration by adding Wi-Fi and Ethernet interfaces, providing more convenient remote connectivity, data transmission, and network integration. These upgrades empower seamless communication and smarter interconnectivity across modern precision farming and automation ecosystems.
Reliability reinforced for harsh field conditions
Designed for long-term reliability, it is built with an IP67-rated enclosure, ensuring dependable operation in dust, mud, rain, and other harsh outdoor environments.
Its new metallic base significantly improves mechanical strength and durability, extending the device’s service life and maintaining stability under vibration and impact – ideal for rugged agricultural or construction machinery.
Enhanced functionality and smarter maintenance
T81 continues to support Navynav’s proven technologies, such as Terrain Compensation, Slide Smoothing Algorithm, and Single-Antenna Heading, ensuring precise operation, stable path planning, and smooth control performance in the field.
Beyond that, T81 introduces powerful new features including remote diagnostics and Over-the-Air (OTA) upgrades, allowing users to monitor, troubleshoot, and update devices remotely. These capabilities reduce maintenance costs, minimise downtime, and enable efficient fleet management from anywhere.
Conclusion
With its high-precision all-in-one antenna design, versatile connectivity, and robust reliability, the smart antenna T81 sets a new benchmark for intelligent GNSS positioning solutions. Whether in smart agriculture, engineering construction, or autonomous operations, it empowers users with accurate, stable, and connected performance – anytime, anywhere.
